Abstract

Polyimide resin compositions that contain an aromatic polyimide, graphite, and acid-washed kaolinite are found to exhibit high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to high temperatures, such as bushings, bearings, and seal rings that are used in aerospace, transportation, and materials handling applications.
